Java Java Objects Harnessing the Power of Objects Increment and Decrement

I am having a difficult time with this method. Please help

I tried to create a new method. Then it came back as "task one is now invalid" then if I go back to task one...and I do not change anything it says it is correct. I am very confused.

GoKart.java
class GoKart {
  public static final int MAX_BARS = 8;
  private String color;
  private int barCount;
  private int lapsDriven;

  public GoKart(String color) {
    this.color = color;
  }

  public String getColor() {
    return color;
  }

  public void charge() {
    barCount = MAX_BARS;
  }
  public boolean isBatteryEmpty() {
    return barCount == 0;
  }


  public boolean isFullyCharged() {
    return MAX_BARS == barCount;

  }
}
public boolean drive() {
  return lapsDriven == 1;

Drive is a method of the class GoKart, format the 'drive' method you created so that its still inside of the class.

You don't need to return anything you just need to increment the variable, because of that you can get away with defining the method as "void" instead of "Boolean".

class GoKart {
  public static final int MAX_BARS = 8;
  private String color;
  private int barCount;
  private int lapsDriven;

  public GoKart(String color) {
    this.color = color;
  }

  public String getColor() {
    return color;
  }

  public void charge() {
    barCount = MAX_BARS;
  }

  public boolean isBatteryEmpty() {
    return barCount == 0;
  }

  public boolean isFullyCharged() {
    return MAX_BARS == barCount;
  }

  public void drive() {
    lapsDriven++;

  }
}
